From Calvin’s comments on Luke 24:32, “Did not our hearts burn within us while [Jesus] spoke to us on the road, while he opened up to us the Scriptures.”

It cannot be doubted that he then engraved an uncommon mark on the hearts of these two men, that they might at length perceive that in speaking he had breathed into them a divine warmth… Yet let us remember that it is the proper fruit of heavenly doctrine, whoever may be the minister of it, to kindle the fire of the Spirit in the hearts of men, to purify and cleanse the affections of the flesh, or rather to burn them up, and to kindle a truly fervent love of God; and by its flame, as it were, to carry away men entirely to heaven.
